Question Is a 500W PSU enough??

[mwillmers1]

Currently purchased an EVGA 80+ WHITE 500W, as this is all I can afford with in my current budget but Im a bit unsure whether it will be enough to deal with my current build.

I've listed the build as below

1. Motherboard- MSI H61M-P31 (G3) MS-7788 VER 1.0 LGA1155
2. CPU- Intel I5 3470
3. CPU Cooler- cooler master 412R
4. Ram - 2x Corsair Vengeance DDR3 4Gb 1600Mhz
5. Hardrive- Toshiba 1tb PC300
6. Graphics- Evga GTX1050TI 4gb superclocked (min rec PSU 300W)
7. 2 x 120mm fans Front & back
8. 1 x Litreon DVD/CD RW

Any advice would be great

Cheers

Not a great PSU in terms of quality , but it can easily power those specs. Not much power being drawn there.
Your all set.

Yup, fine with a 1050 Ti, but if you ever make a significant upgrade, a new, higher-quality PSU will likely be recommended.

It will be fine running that low power draw spec.

ive just noticed its got multiple rails on that psu, 12v 40A, 3.3V 24A, 5v 20A.

Ive never used one of those before always used single rail ones, is there much difference on doing the connections with this would I need to balance any loads?

im thinking of paying the extra £13 and going for the bronze rated single rail version now, to purchase this one it'd be £31, or its about £44 for the bronze rated one

 

[Dark Lord of Tech]

12v 40A is a single rail PSU.

Single 12v rail:

so it is, just checked the pic on the side of the bronze one and table of loads is the same . I never usually bother even looking at them feel like such a muppet now

 

[mwillmers1]

so why do they need them +5V, and 3.3V rails for?, Im guessing its maybe to save costs in manufacture?

[mwillmers1]

nice1 that's explained it all there, so its basically its standard to have them two other rails in order to prevent having to put one massive rail in. When people say about multiple rails and balancing loads this is where you have multiple 12V rails i.e. 2 x 12V 20A, or 1 x 12 20A + 2 x 12V 10A

Some PSU's are still designed with multiple 12v rails , it's not always a bad thing.
