The CoolerMaster CAC-T05-UW computer case is a Mid-Tower computer case.

It supports (Uses) power supply's that are the ATX form factor.

[Motherboards dimensions are stated as Form Factor. What Form Factor is the motherboard.
The term Form Factor is used erroneously for Power Supply's, and computer cases,

http://en.wikipedia.org/wiki/Computer_form_factor ]

The ATX form factor dimensions for a Power Supply is approximately,
A) 6 inches Wide. { Width} (15.24 Centimeters)
B) 5.5 inches Long {Length} (13.97 Centimeters)
C) 3.5 inches Tall {Height} ( 8.89 Centimeters)

The ATX form factor for a power supply, also denotes what power cables are used.

A) One 20 or 24-pin ATX main power cable.
(Power supply's sold now, have an ATX main power cable that can be used as a 20-pin, or a 24-pin. You simply use, or do not use the four extra pins,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20plus4

B) One 4-pin ATX +12 Volt power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

C) At least one SATA power cable. Better power supply's have two, or more,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

D) Two, or more 4-pin standard Peripheral power cables. Better power supply's usually have four,
(Misnomered as 'Molex'. The name stuck just like Crescent wrench for an adjustable open-end wrench),

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

[Don't forget that if you need a certain power cable, and the Power Supply doesn't have it, you can use an adapter power cable on two 4-pin standard Peripheral power cables ]

E) 4-pin small Peripheral power cable. Used in the older computers for a Floppy Drive. Used now for a Card Reader,

http://www.playtool.com/pages/psuconnectors/connectors.html#floppy

I'm going to state that approximately 80 percent of personal computers out there use an ATX form factor power supply.

(The rest use a smaller size of power supply, or a different shape.
This was brought about so desktop computers could be made smaller.
Less space is needed for the computer tower in the room.

BAD design, computer manufacturers, and people who desire this.
Most personal computers are cooled by AIR, except for the gamer computers that may use Water, or Nitrogen, or refrigerant.
You need a Mid-Tower, or Full-Tower computer case, or you're going to have problems down the road)

ATX power supply's are sold everywhere.

The things you need to consider, besides what form factor for the Power Supply, is what Wattage, and how much Amp's will the 12 volt power rails handle.

A decent Power Supply now should have at least 500 Watts, and the 12 volt power rail/s should handle at least 24 Amps. (24A)

{Some Power Supply's are listed as having multiple 12 Volt power rails.
Check to see what Each 12 volt power rail listed, will handle in Amperage.
Add ALL 12 volt power rail Amp's up for a total.
This is what the 12 Volt power rail amperage will be.

I'll show an example in an added Comment}

For additional questions please post in a Comment.

eMachines uses low quality hardware components inside their computers. This is the way they can sell them at budget prices.

One main hardware component is the low quality power supply they use.
A generic power supply made by Bestec. (A generic power supply manufacturer)

(PSU. Power Supply Unit. The type of PSU used is a SMPS.
Switched-Mode Power Supply,

http://en.wikipedia.org/wiki/Switched-mode_power_supply )

Low quality;
A) Electrolytic Capacitors (Radial Aluminum Electrolytic Capacitor)
B) Rectifier Bridge
C) MOSFET/s
D) Wiring is too small in gauge
to name a few of the components.

However IMHO it is also best to check out the Power On switch.
There is a simple test to see whether the problem is a faulty Power On switch, or a faulty Power Supply.

The test involves bypassing the Power On switch. The Power On switch is not involved in this test.
A jumper wire is used on the Soft Power On wire, [ PS-ON ], and a Ground wire in the ATX main power cable connector.

If you bypass, and the Power Supply comes on you have a bad Power On switch.
If the Power Supply does Not come on you have a bad Power Supply.
If you would like to know more in detail on how to perform this simple test, simply post so in a Comment.

The Power Supply used is just a common ATX version.
ATX refers to the Form Factor of the power supply.
Regular size ATX form factor is approximately 6 inches Wide, 5-1/2 inches Long, and 3-1/2 inches Tall. (Height)

There are also differences in the pinout of the ATX main power cable.
Yours may have 20-pins, or 24-pins.
Power Supply's sold now take this into consideration.
Their ATX main power cable can be used as a 20-pin, or a 24-pin version.

[ General example of a 20-pin ATX main power cable, and it's connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

Example of a 24-pin ATX main power cable, and it's connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

Your motherboard may also require an additional power cable, commonly referred to as a P4 power cable, or P4 ATX 12V power cable, or just ATX 12V.
The actual name is 4-pin ATX +12 Volt power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

If you would like help in finding an inexpensive reliable Power Supply, please post in a Comment.
I will need to know what Model Number of eMachine you have. It's on the back next to the Windows product key, or up on the side of the computer tower.

If you need anything explained that I have stated here, please let me know in a Comment.

Presuming you mean the Earthwatts 500:
Should work, though the Earthwatts has the 24 pin ATX instead of the 20-pin.
http://www.atxpowersupplies.com/manuals/Antec-Earthwatts-EA-500D-user-manual.pdf
You just need to snap the 24-pin connector apart to make it work as a 20-pin. It can be snapped back together for future motherboards.
The Bestec is just a standard ATX power supply

The green light flashing is a diagnostic LED light, telling you there is a power failure.
More specifically a bad Power Supply.
Weak voltage power rail.

The Power Supply used in a Compaq Presario SR1010Z desktop computer, is a 300 Watt unit, and is an ATX form factor.

[ATX form factor for a Power Supply, denotes the size of the Power Supply case, and the shape.
It is approximately 6 inches Long, 6 inches Wide, and 3-1/2 inches Tall.
The ATX form factor for a Power Supply is used in over 90 percent of the personal computers out there, and is as readily available as the air we breathe]

Usually, HP uses one of three generic Power Supply manufacturers.
1) Bestec
2) Delta
3) HiPro

All are low quality Power Supply manufacturers.

This is HP Support, and the main menu page for the Compaq Presario SR1010Z desktop computer,

http://h10025.www1.hp.com/ewfrf/wc/product?product=1146324&lc=en&cc=us&dlc=en&submit.y=7&submit.x=6&lang=en&cc=us

If you click on Manuals, then on Upgrading and Servicing Guide on the following page, there are instructions on how to open your computer case.

This is instructions on how to replace a Power Supply, from HP Support,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01356113&cc=us&lc=en&dlc=en&product=3548196

(It's for a Pavilion a6230n desktop computer, but after you open the computer case of your Compaq Presario SR1010Z, the instructions are the same)

What Power Supply would I recommend?
There are 100's to chose from.
This is but one example,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3276575&CatId=1078

Chosen because;

1) Maximum wattage is rated at 450 Watts.

A computer ONLY uses the power it needs, and NO more.
Wouldn't matter if you had a 10,000 Watt power supply, (No such thing. An exaggeration), if your computer only needs 100 Watts, it would only use 100 Watts.
(Surfing the internet typically uses 100 watts)

2) Has all the power cables you'll need, and more. Tie up the power cables you do not need. (Use plastic ties, Not wire, or bread wrapper ties)

3) 24 Amperes (24A) on the 12 volt power rail.

4) 135mm cooling fan.
The cooling fan on the Power Supply you have now is 80mm.

A larger fan turns slower. Produces as much air as a smaller fan, (Or more), but makes less noise.
Less wear on the fan's bearings also.

5) Is an ATX form factor Power Supply.

6) It's 80 percent efficient, compared to the 60 percent efficient Power Supply you have now.
(That is, if it was working)

1. remove the battery
2. Press power button now. keep power button pressed for 2 mins
3. Reseat the battery.

see if it works !.
Happy Computing. !!!
Else please aloberate.
