Installed New Power Supply PC is Sluggish

TwistedFury · Jun 25, 2014

I replaced my 480w Logysis PSU because it was bad, no PCI-E plugs so I had to use an adapter, I just upgraded to a 650w Sentey PSU to match my case, and it has 2 PCI-E 6 pin cables, and I was glad because I could give it my GPU some real power, but after booting it up (This is the first time booting it) Everything seems sluggish, I haven't tried games yet but I plan on it, is my GPU not plugged correctly? Is my system accustoming to the new power supply?

An upgrade from a Logysis to a SENTEY is not an upgrade they are both very very poor power supplies.

This is a SEASONIC a huge upgrade.

Atleast it didn't have adapters, the adapters were killing my GPU, which is why I got it.

Don't run the Sentey for long they aren't very reliable and can fail and damage other components.

TwistedFury · Jun 25, 2014

It won't damage it as much as my Logysis was, my GPU was frying, this one keeps it cooler, could just be bad experience in the past with it.

Just letting you know Sentey's aren't much better.

Have a good one.

I see, and thanks, my PC seems to be speeding up, turned out I left some cables loose, thanks though! The new PSU has stopped all my graphics crashing and bugging.

http://www.sentey.com/en/erp-650-watts is what I got.

send that psu back. a 450w antec or seasonic unit would be better.

TwistedFury · Jun 25, 2014

I needed more watts for a GPU upgrade, I wasn't going to reduce the watts....

TwistedFury :

just because a psu says 650w, doesnt mean it can produce 650w under continuous load, or have enough of those watts on the 12v rail. many quality 450w rated units test more powerful than "650w" budget units when reviewed/load tested. It is a known fact many psu manufacturers misrepresent their watt ratings, often stating peak watts, or just plain failing that the psu lives up to the claimed wattage.

This. A great quality 450w PSU is better than a no-name 1000w PSU.

If you bought it from Amazon, return it.

Get the XFX TS 550 for $26 after $25 rebate and $10 coupon.

There is a way to measure if the power supply is good or not by comparing the Amps with the stated wattage.

I wish I was making money recommending the power supply to you but I am just a neckbeard.

Pondering :

no, the way to measure if a psu is good or not is to load test it.

A good analogy is power rating of speakers. You can buy a set of speakers that is 1000w PMPO, but are only 15w RMS. The manufacturer will use the PMPO (Peak output) on their advertising because it looks more impressive. PSU companies often do the same thing, and some just plain lie about the wattage rating.

Any 650W PSU that Cost $39.00 NEW is a risk to run in any system.

The reason it's $39.00 = JUNK.

TwistedFury · Jun 26, 2014

I understand, thanks, but I am only 14 and don't have the means to buy good stuff, ya know?

Dark Lord of Tech · Jun 26, 2014

That's even more of a reason to buy a good PSU , the power supply is the heart of the system it runs and protects the other components.

Keep a good eye on your system with that PSU in it.

Everyone here wants the BEST outcome for your computer.

I was about to get one of those Senteys from Amazon.... Id rather get one of those Shark's though...there is a bunch of decent cheap PSU's that are actually pretty good believe it or not....

Dark Lord of Tech · Jun 26, 2014

Here's what happens to a system with a cheap PSU.

What are you a Corsair Rep or something? haha, come on man Corsair has/had some crap PSU's too.....

Dark Lord of Tech · Jun 26, 2014

It was a testing bench , it's actually a Raidmax PSU that is still on the market.

Fidgetmaster · Jun 26, 2014

Raidmax are known to blow up.....

Dark Lord of Tech · Jun 26, 2014

A lot of poor supplies have done that.

Fidgetmaster · Jun 26, 2014

like right now I have cheap Solytech 400w PSU I been using and by all means it should of blew up by now haha.

TwistedFury · Jun 26, 2014

My PSU can't be that cheap, it's possible to sue because of physical danger right?
