Hello,

My PC i'm building (On a budget, and looking to do video rendering)

- FX 6100 (Bought bec. deal -$70 on MOBO)
[ ^I've never OC'd but i want to try to OC to 4.0ghz would be enough for me. ]

- ASRock 970DE3/U3S3 AM3+ AMD 770 SATA 6Gb/s USB 3.0 ATX AMD Motherboard

- 500GB Western Digital Blue HDD
(On a budget idc, about SSD at this point haha)

- SAPPHIRE Vapor-X 100358VXL Radeon HD 7770 GHz Edition 1GB
(Had a 550ti in my last pc, but i felt like trying the 7770)

- G.SKILL Ripjaws Series 8GB RAM

- Windows 7

I plan to get a Rosewill 600w, its on sale, but to save money do i need 600w?

Or is 500w sufficient enough?

Thanks a lot.

500 will be plenty unless you want to sli/crossfire or overclock later. Rosewill is good, Coursair, Ocz, Antek, are other good brands.

How many amps on the 12 volt rail of that current power supply? if it is a multi rail it should have a combined number in either amps or watts.

any quality 500 will run that system with power to spare. I have run slightly more power hungry on a 300 watt(i5 750 + 5770 and 2 hard drives.).

I ask about the 12 volt rails because i have seen some 500 watt power supplies with less then my 300 watt unit.

I was looking at these two PSU's

500w (1 Rail) (i had a 600w version of this before, and it worked nicely)

Rosewill 600W (2 Rails)

Both those pages are unavailable right now. Do you have the complete specs?

The 500w has 28a on the 12v rail. The 600 has two 19a 12v rails. The 500w is bronze so will be a little more efficient. Either one would work.

I think that was supposed to me 38 the other has 35(interesting that the 600 watt delivers less power on the 12 volt rail, but common with older designs, this is not as bad as many I have seen). It is a trivial difference at best and both are more then able to run your system.

I would personally get the 500(with its 5 year warranty vs the 3 year on the other unit) watt because it is a newer design with auto voltage range and all that good stuff.

Ooops, my mistake. Yes, go with the 500.
