Question about Intel H55TC Motherboard Core i3 540 Processor w Fan Bundle FREE Napoleon Total War Game (BOXDH55TCWCI3540GAMEBUNDLE)
A quick look at the H55TC's architecture tells me you should choose - at minimum - a power supply
that is ATX12V 2.0 compliant. This will provide you with a contiguous 24-pin connection to the CPU,
increased power on the 12V rails, and adequate power to most of the board's optional components.
That's the short answer.
From there you need to take a look at how you intend on completing your build. Are you going to use the onboard graphics or pop in a discrete video card? If the latter, then you should be looking at
PSU's that are ATX12V v2.2 compliant, to provide adequate power to the PCIe x16 slot. But keep in mind that ATX12V v2.2 revision limits 12V rails to 20A per rail, which means if you plan on building a performance machine that begs for 60A of power, you'll be limited to power supplies with split 12V rails. Multiple 12V rails introduces load-balancing issues and other concerns, if your plan is to push this system to its limits.
Moving up to the ATX12V v2.3 form factor removes the 20A per rail restriction, allowing for high-amp
single 12V rail power supplies. This revision also ensures higher efficiency ratings (80% on avg.) which means less power consumption, and less heat build-up in your case.
The optimal choice would be an EPS12V compliant power supply, a revision made specifically with multi-core processors in mind. My pick for one of the best value EPS12V power supplies would be the CORSAIR CMPSU-750TX - currently on sale at Newegg for $109.99 (30-bucks-off.)
It delivers a true 750W of power; pumps out 60A on a single 12V rail; is both SLI & Crossfire certified; 80%+ efficient; Core i7 compatible - essentially future-proof for the life of the PSU.
Finally, here's a link to a pretty decent power supply calculator by Asus. It should give you a good idea of how much juice you're gonna need once you trick out your system.
Good luck, and I hope this was useful :)
