Do I Have Enough Watts?

[mcastellanos6]

Hi everyone,

First off,here are my specs:
Mobo: Gigabyte GA-790XTA-UD4
CPU: AMD Phenom II X4 955 3.2GHz BE
GPU: XFX ATI Radeon HD 5770 ( HD-577X-ZNFC)
PSU:Antec TP-650W
Case: Cooler Master CM 690 (with 3 120mm fans
HDD: Hitachi Deskstar 500Gb 7200Rpm, 16MB, HD30500IDK/7X
Ram: G.Skill (2x2G) DDR3-1333 PC3-10666 (CL8-8-8-21 @1.5V)
Disk Drive: Lite-On 24X Sata DVD-RW (iHAS324-98)
OS: Windows 7 (64-Bit)

This is my 1st build and i want to add some bells and whistles (more fans)LOL. So my question is..... Can my PSU handle two more fans? (ONE 140mm fan + another 120mm fan) (the case came with three 120mm fans (front, left, & back)

Easily. My old Athlon 3200+, with two IDE HDDs, one at 5400RPM and the other at 7200RPM, two DVD RW combo drives and a GeForce 6800 are running fine on a 300W PSU, besides, the HD 5770 is very energy efficient.

you could probably crossfire in a second GPU with that PSU, no worries. its an antec, so good quality.

should be golden.

The answer to your question is yes.

As welshmousepk pointed out with the Antec TruePower 650 you actually have enough power not only for additional components but also two ATI radeon HD 5770 video cards in Crossfire mode.

Here are the official ATI recommended power supply requirements for the ATI Radeon HD 5770 and 5750 video cards:


450 watt or greater power supply with one 75 watt, 6-pin PCI Express® power connector recommended.

600 watt or greater power supply with two 75 watt, 6-pin PCI Express® connectors for ATI CrossFireX™ technology in dual mode.


The recommendations are for an entire pc system.

It is a TP however. Like the SP it has suspect caps. Keep it as cool as you can and you should be ok. I'd consider replacing it when you have the $$$.

Huh?
If it's a TPN it's full of Nippon-chemicons, not the Fujihyu's that caused the issue's.

delluser1 - I had to take another look. OP just said Antec TP-650. Nothing else. Can't tell if it's a an older TP or the TP New.

 

[delluser1]

Even the TPT used OST's and a Hitachi main.
They are getting harder to find simply because they are older tech, can't imagine anyone buying one today with all of the better quality options on hand.
There never was a 650 watt version of the True Power 2.0.

 

[JohnnyLucky]

OK! Lately I've been recommending the TP New over the TP.

 

[4745454b]

So its a TPN? I saw TP and know that sometimes people upgrade their computer but continue to use the old PSU. I wouldn't trust my new computer to an old PSU with bad caps. Thought I'd point it out just in case.

 

[mcastellanos6]

Yea it's a TruePower NEW 650W

 

[logan the huge]

Unless there's some other TruePower series out there, I believe the TP-xxx designation is exclusive to the TruePower New series.

EOL'd
TruePower = TRUExxx
TruePower 2.0 = TPII-xxx or TP2-xxx
TruePower Trio = TP3-xxx
Current
TruePower Quattro = TPQ-xxx
TruePower New = TP-xxx

Why TP instead of the more logical TPN? My theory is that the decision to add "New" to the designation occurred after production began since the labels on the physical units don't actually say "new" anywhere on them.

Logan - Antec managed to confuse everyone, including me. There's the older original True Power series which is still available. Antec also has the True Power New series which is supposed to be a new and improved version. It's very easy to get the models mixed up.

 

[logan the huge]

^No, I think you misunderstood what I was trying to say. The old TruePower is from 8-9 years ago.

Here are the reviews of the TruePower New 750w:
http://www.hardwaresecrets.com/article/766/6
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=140

You can see from the pictures that PSU label clearly just says "Truepower 750" even though the boxes say "Truepower New". There has never been a TP-550/650/750 that wasn't a "New", that's the point I was trying to make. The "Truepower New" line isn't a revision of something else, it's a brand new series that replaces the "Truepower Trio".

If you can find any review or product listing of a non-"New" Truepower TP-550/650/750, then I'm perfectly willing to admit to being wrong.

Logan - This is the beginning of the jonny guru review from March, 2009 you linked to:

"Way back in the day, Antec came out with a new power supply line called the Truepowers. When these were introduced, they promised groundbreaking stability at reasonable prices for us consumers. As time passed, the Truepower line evolved and changed. We soon had the Truepower II series, and then the Truepower Trio series."

"Well, get ready folks because it's happening again. Antec just sent me what you see in the above picture, the latest unit to bear the Truepower moniker, the Truepower New 750W. These new Truepower units start at 550W and go up to the 750W model I'm looking at today."

See - No wonder I'm confused.

Too many True Power models over the years. And let's not forget True Power Quattro. Then there's Neo Power too! Someone else has Tough Power and Real Power!! What's next? Several versions of Antec Nuclear Power? No! Wait a minute! That is not politically correct. The next new version would have to be "True Power Green and maybe even "True Power Blue" for those who like blue led's." Users could shorten that name to "True Blue!"

It is not a technical review but here is a link to the original TruePower 550:
