TOPOWER Galaxis MX500W PSU - $25 - Page 2

It is not 80+ Certified, comes with a 1 year warranty (most quality PSUs are 3 - 5 years), doesn't even look like it has active PFC. Basically this is very low quality, and not recommended for anything that you might care at all about.

You'd be far far far better off with a Corsair CX430 for near the same price. It provides just as much 12V power, more reliably and is of far superior build quality (despite not being that great).

Sorry didn't realize this post is days old, my condolences to those who bought.
Except the CX430 is not the same price. The CX430 is $45, or almost double the price of this Topower PSU when it was on sale for $25. This PSU is perfectly fine for a lower power cheap build, certainly better than getting a $25 coolmax.

And when it says 336w on the 12v rail, they mean it can do at least 336w on the 12v rail. This PSU isn't a 500w, but it does seem like a decent and cheap 400w.

1. The main plugs are on the outside of the psu. so if it's gonna be bottom mounted with the fan at the bottom grill the 24 pin and 8 pin are at the front of the case and not at the motherboard tray. Weird.

2. The Sata/IDE cables are all mixed.
sata-ide-sata-mod connector
floppy-ide-sata-ide-mod connector

I don't know who in hell designed this specific model but they should get fired.
Performace wise the thing seems to be ok. its been running all night just with the paperclip mobo and the fan is almost dead silent with no heat issues.
Whats the point of running it like that? There's no load on it.. :S FAIL!

For 25 bucks it would be perfect for a budget build. And it has 2 PCIe pins.
It has a voltage selection switch. That means it probably is a 5+ year old design.


The way it rated, this is probably a mediocre (at best) 300w PSU.

Don't bother.

The CX430 does go on sale for ~$30-35.

How do you know this PSU is better than a Coolmax?

No where does it say it can do 336w on the 12v rail. It says it has two rails each capable of up to 14A. This does NOT mean both can be providing 14A simultaneously. The way it is rated and designed, it probably is a crappy/mediocre 300w.

Pricepoint reasoning for validating a "psu purchase" is least to say poor.
Good points are
*RMA service / Customer (even the good ones fail so the ease of returns goes a long way)
*Branding (word of mouth counts alot)
*Personal experience (if you can get away with a using a cheap psu then you rolled the dice and survived the odds > saved money > win)

Quite honestly dell computers (business environment) of past (and maybe even today) put crappy psus and they actually last beyond the warranty of the unit. Thats not to say that they have poor business ethics. It just works. And they sell alot.

If you're going to use price as validation, the CX430 can be had for ~$15 when it's on sale.

Yup, if you ever see a PSU with a red switch on the back (passive PFC), don't even bother.

There decent. I have almost the same model except not modular running in a server that runs 24/7 for 3 years now so if this one last for half that for the $25 I paid for it it'll be a great deal.

Actually I just remembered that the OCZ Powerstream PSU that's in my girlfriends computer is made by Topower....that's been running for around 4 years.
