Do I need a new power supply?

[ifarted]

Hi, I was wondering do I need a new power supply if I want my computer to run its full speed.
Would my 400 watt power supply allow my computer to run its full potential or I need to get something higher like 550watt?
My computer specs:
- dynex dx-400wps power supply
- GIGABYTE GV-R667D3-1GI Radeon HD 6670 1GB 128-bit DDR3 PCI Express 2.1 x16 HDCP Ready Video Card
- OCZ Vertex 3 VTX3-25SAT3-60G 2.5" 60GB SATA III MLC Internal Solid State Drive (SSD)
- 320gb 7200rpm hard drive
- ASUS M5A97 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard with UEFI BIOS
- CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMZ8GX3M2A1600C9B *********(In my bios it says its running at 1300 instead of 1600)********
- Amd FX 8120 Processor Black edition
-Cd/Dvd drive
- 5 fans, 6 fans including the psu fan
- corsair hydro series h60 high performance liquid cpu cooler (push/pull)
Here are some pictures:

If you're overclocking and your system is stable, you should be fine. A power supply either supplies enough amps or doesn't; too much won't improve performance. I've used the dynex ps you have; it's barely adequate. I use a 400w ocz, but my sempron with 210 video doesn't need more juice. If you want to replace the ps, it can't hurt, and I certainly would with your next video upgrade.

However, I would personally upgrade the PSU to something like a Corsair CX430V2 even if I weren't going to upgrade the GPU anytime soon, I just can't trust it enough.

 

[ifarted]

If i were to upgrade could you provide me a link of some? I'm trying to spend under 50 because i don't have much cash on me atm

Here's the CX430V2 http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026&Tpk=cx430v2

Here's the CX430V2 http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026&Tpk=cx430v2

that only provides 30 more watts than my current one

It's not only just 30 watts, it's 430 watts of stable and reliable power. Wattage doesn't matter as much as reliability does.

 

[ifarted]

what about the CORSAIR cx500?
i may upgrade my gpu in a month or 2

 

[mocchan]

Yes, that's also a very nice option for you to upgrade Just make sure it's the CX500V2.

Dynex is complete crap. Having a better power supply will not make your computer perform any better though but it will reduce the risk of having a low quality piece of junk damage your other components.

HardOCP review of the PSU.

It's one of the worst power supply reviews I have ever read. Basically the summary is that the model should be labeled at 200 watts.

The Corsair 430CX listed above actually produces it's rated wattage and is very good unit. It's a huge upgrade from what you have.

Oh gosh Dynex/Rocketfish, Best Buy....

Get a 500W.

im deciding either

Corsair.

 

[ifarted]

whys that?

 

[Deleted member 217926]

The Corsair or the Antec. Coolermaster makes great cases and cooling accessories......power supplies, not so much.

I trust Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone, Enermax, OCZ and Antec across the board.

how much watt is my computer using at idle load and max load?

 

[Deleted member 217926]

Your computer needs a 400w power supply.

It is of course better it the PSU can actually put out 400 watts.

i been using this power supply for about half a year. Could it be possible my gpu or cpu is damage now because it has lack of power? I did notice my computer shut down by it self and restart but no more than 5 times

ifarted, you need not worry about wattage so much. I've talked to builders who think that you need a 1000+ watt power supply for any modern computer that can game, and that's simply not true. I have a 650w corsair professional, and, when needed, it can give me 900w. Even the 650w is more than enough to power my computer - I'm actually sitting right in the sweet spot of 60% load that makes a PSU the most efficient. It'll never die on me, and it'll never kill my computer.

Do a little research on what brands of power supplies are reliable - this is WAY more important than having too many watts, as a bad power supply can either quit, or fail in a way that bricks your entire computer. My personal list looks a lot like anorts, but I'm not as big on enermax, ocz, or antec.

No. No computer part will ever fail because it doesn't have enough power, only because it has too much voltage from user error.

Even if a part isn't getting enough power, the worst that will happen is that it will turn off - like you may have had happen. [There are dozens of other reasons a computer may restart on its own as well.]

Try this

RAIDMAX RX-500AF
$44.99 - free shipping
10% off w/ promo code PSUSEP12
$40.49 after promo code

a 500w PSU with good ratings at a great price

 

[ifarted]

so if i have a power supply that is 1000w, it would damage my computer parts because of too much voltage?

That has 2 +12v which isnt that good. Each +12 is only 20amps

No - the only way you would damage your parts from that is if, while overclocking, you were being an idiot.

Also, I'm not sure what we're saying is getting through... 1000w would be WAY too much for you, it's not even twice what you need; closer to 3 times.

Stop worrying about the wattage: as long as it's enough, the number doesn't matter. What matters is that the power supply isn't going to break and melt your entire computer.

Which is enough to run cards that take up the max wattage of the psu. Check youtube videos of people using the psu to power nvidia 570s. If your only willing to spend a bit, you should not expect to run top of the line gear.
